I'm in the middle of the court process for a Restraining Order, and I just received a blocked call, now what?

I received a call on my Sprint cell phone from a blocked number at 5:26AM this morning, while I was sleeping. The last time I received these random middle of the night blocked calls, was just the night or early morning prior to filing for the order of protection. If the respondent contacts me, then it is a violation of the Temporary Order of Protection. However, if I continue to receive blocked calls...how will I ever know if it is HIM violating the order? I know Sprint will not p along this information, because I already attempted to go about getting a Call Detail Report yesterday for the previous Blocked numbers, and they said they do not keep touch of calls that either I do not answer or do not go to voicemail, as in taking up minutes. I do not want to be a pest, nagging the police with my allegations anymore, unless I am sure they might be able to be of istance. Is there any possible way that I can unveil the source of this blocked caller? Would my local police be of any istance, since it could possibly be a violation of the Temporary Order of Protection?
